Getting started


Ensure that JRE 1.8 or higher is installed in your system. Also ensure that 8080 TCP port is free.


Download MSI installer from releases page. Double click on it. Currently installer is unsigned. It leads to red alert during installation. Do not afraid: it's OK.

Linux and macOS

We've prepared universal installation script. Just run this command in your terminal.

curl -sL | bash

Getting started with CLI

Run node

Then we need to run local node. First of all lets build initial coin distribution config.

pravda gen address -o my-wallet.json

This command will generate ED25519 key pair. It's a valid Pravda wallet. Now you can add an address to coin distribution config.

    "address": "address from my-wallet.json",
    "amount": 1000000000

Save this to my-coin-distribution.json. Now lets initialize node configuration.

pravda node init --local --coin-distribution my-coin-distribution.json

Congratulations! The configuration is written to pravda-data/node.conf directory (also you can chose data directory using --data-dir key). Now let's run the node.

pravda node run

Now you have our own Pravda network with one validator, and one billion coins on your account. Check out http://localhost:8080/ui.

Transfer coins

You are very rich! Now you want to donate a part of your wealth to some poor guy. Let's generate wallet for him.

pravda gen address -o another-wallet.json

Wallet for poor guy is created. Now let's copy his address and transfer some coins.

pravda broadcast transfer \
  --wallet my-wallet.json \
  --to <address-of-poor-guy> \
  --amount 1000000

Now the poor guy is not so poor. Great job!

Write your Pravda Program

Importing Project Template

To use project template you will need .NET Core SDK 2.1.
Create a directory for your project and run inside it:

dotnet new -i Expload.PravdaProgramTemplate
dotnet new pravdaprogram --namespace MyTeam --version 1.0.0 --name HelloProgram 

Now your directory contains: - HelloProgram.cs - main program file. By default it contains simple program with HelloWorld method - HelloProgram.csproj - project configuration. It includes scripts for compiling and deployment, as well as .NET dependencies & metadata - - feel free to consult it whenever you feel confused

Compiling the Program

To compile C# code into pravda binary run:

dotnet publish -c Debug

Now you have MyProject.pravda in your project directory.
You can use local node and Pravda CLI commands to deploy to a local node or proceed further to work with Pravda Testnet.

Deploying to Testnet

Let us generate a Pravda Wallet:

pravda gen address -o wallet.json

If you already have a Pravda Wallet, move it to project folder and rename it to wallet.json.

Go to Testnet Faucet to get some XCoin, as you have to pay for deployment transaction.

Finally, run:

dotnet publish -c Deploy

Now your program is on the Testnet! Your project directory includes program-wallet.json which has your program's address.

If you want to update program run

dotnet publish -c Update

For more information on working with the template, see in your project directory.
